' My invention. relates to material handling apparatus 'and more particularly to instrumentalities for use in `constructing masonry and other briclr work. Y

Objects and advantages of the invention will be set forth inpart hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention,- the same being realized and attained by means 16 of thev instrumentalities and combinations pointed out inthe appended claims. n The invention consists in the novel parts, construction, arrangements, combinations and improvements herein shown and lde- 15 scribed. i Y

The accompanying drawings, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and

l together with the description, serve to eX- 20 plain the principles of the invention.

Of the drawings Fig. l is a sectional view' showing the present preferred embodiment of'my invention; Fig. 2 is a plan view of the apparatus ac- 2'5 cording to my invention in place over a sewer to be provided with a manhole; Fig. 8 is a detailed sectional view taken on lineS--SofFiglg w y Fig. 4 is a detail of the interengaging spanners'employed in my, apparatus;

The object ofmy invention is to provide a material handling apparatus-forV use in construction of masonry and brick work and more particularly for use in construction of man-holes such as are commonly built in connection with sewers, which apparatus vwill greatly facilitate such construction and materially increase the safety and convenience of the workmen employed in Vsuch construction. l Y 1 Broadly considered, my invention consists in a plurality of upright and preferably converging guiding -or supporting members which can be erected around-the space in which the manhole or other construction-is to be built-,with means `for spacing and holding these members in proper'positionv Along these members are variably and slidably positionable instrumentalities for receiving and transporting construction A material to the Workman engaged in the construction work, suchl instrum-entalities preferably comprising mortar' vand brick receiving and holding means which are guidedby the upright members and may,'after being loaded, be lowered to the level of the Workman. Preferably, although not necessarily, these instrumentalities are so guided by and mounted on the upright members'that they hang Vinwardly towards the center of the area defined by the several upright members. rlhe upright members may also be used` as guides'to properly gauge the construction Work and'thereby secure the proper slope on the manhole or similar structureV being built.

My invention provides asimple, relatively inexpensive structure bywhichasingle work- 5 lman is enabled to construct av manhole or other similar construction lin `a very sexpediti'ous manner and greatly-lowers thecost of suchv construction. y y

-' Referring now in detail to the'accompanykw ingdrawings forming part ofr this application,'the* invention'is shown as specifically applied to the construction of a manhole of the type generally used inxconnection with sewers. 7 55 In the drawings there is shown a sewer of the usual construction inwhich a half-section of sewer pipe 10 is laid between two whole sections'1l,ithe manhole to be constructed over the half section of sewer pipe. At each .fg-u

-These sections are joined together byrineans of an interfitting coupling'l4 'slightlysmaller than the interior dia-meter" ofthe pipe, and preferably secured within the lower of the kroo two sections by pins 15. These upright members are placed on the ground at the bottom of the excavation for the manhole and are joined together at their upper ends by means of spanners 17, which space the upper ends of trie upright supporting and guiding members 12 the proper distance apart and at the same time render the structure substantially rigid.

More in detail, the spanners 17 comprise lengths of pipe, provided at each end with a downwardly extending member 18 secured to the pipe by elbows 19, which dcwnwardly extending members are slightly smaller than the inside diameter of the upright members 12and project therewithin. Near the center of each spanner is provided a pair of spaced guides 20, which are interengaging and prevent slipping of one spanner on the other when in assembled position, and yet permit the ready assembly and dismantling of the apparatus. These guides 2O may be secured to the spanners by welding or any other desired means.

The supporting members 12 serve as guideways, up and down which material 'conveying instrumentalities can be moved to deliver construction material, such as bricks and mortar to the workman at the bottom of the excavation.

The mortar receiving and conveying means comprises a receptacle formed of sheet metal, designated generally as 22, which is formed of a curved back portion 28, an angularly disposed front wall 24, a substantially .fiat and horizontal bottom 25 and ends 26. These sheet metal members are preferably held together in assembled relation byl rivets 28 in the usual manner. For guiding the mortar carrier up and down along the upright supports, there is preferably provided a tubular vdisposed at an angle to the receptacle so that as the receptacle is supported on the upright support, it will tend to hang under the inclined portion of the upright support, and will be on the inside of the assembled supports convenient to the workman.

Preferably, and as shown, the frontwall v24 of the mortar receptacle 22 is disposed at such an angle, and the mouth is of such a size that a small amount of mortar will always be on the bottom shelf or ledge 25, so long as there remains mortar in the upper 'or hopper portion of the receptacle, and as mortaris removed from'the ledge 25, more mortar will be fed down from the hopper.

The exact dimensions and angular relation of the several parts will depend to a great extent on the kind of mortar which will ordinarily be used with the receptacle.

For handling and delivering bricks, or the like, to the workman in the excavation, there are provided mea-ns which are broadly similar to the mortar receptacle just described, and these means are shown in detail in Figures 5 and 6. As preferably embodied, there is provided a frame work of rigid angle members 34, securely bolted to boards 35 to form a relatively narrow shelf 36, slightly spaced from a. relatively high back wall 37 and rigid with respect thereto. At the rear of the back wall 37 a tubular member 39 is rigidly secured by stays 40 to the central angle irons 38, angularly disposed with respect to the bac-k wall 37, and so arranged that when the tubular membervis fitted over the inclined supporting member 12, the back wall 37 will be perpendicular, insuring that the device will hang towards the workman and be conveniently placed with respect to him. Angle irons 38 are also provided with extensions 41 at their upper ends, to which a rope 42 is secured for raising and lowering the con# veyor.

Means are also prcvided for raising and lowering the brick and mortar conveying instrumentalities and holding them at any desired position along the upright supports and for t iis purpose, there is preferably provided a depending member 44 provided with short pieces cf pipe 45 extending therefrom to ferm a cleat around which a rope attached to the brick or mortar conveyor can be looped and thereby held in place.

llhen properly erected, the upright supporting members l2 also serve as gauges by which the workman can determine the correct slope of the walls of the manhole, inasmuch as the supporting members are parallel to the sides of the manhole.

ln use, the bottom ends of the supporting members are securely placed in the ground at the ends and sides of the half-section of pipe and spaced the correct distance apart to give the desired slope to the supporting members, the upper ends of the supporting members are then fitted with the intereno'aging spanners, and the workman can descend into the excavation which may then be substantially covered by a. platform or planking 45 to protect the workman against objects being dropped upon him. The brick and mortar conveyors may then be filled with their respective materials and lowered to the level of the workman in the excavation, where they will hang ust outside of the line of the brickwork 47. As the brickwork is erected, the conveyors are held at successively higher levels and are always convenient to the workman.

The invention in its broadest aspects is llf not limited to the specific ymechanisms shown and described but departures may be made therefrom within the scope of the accom# panying claims without departing from the-l principles of the invention and without sacn rificing its chief advantages,

What I claim is l. A material handling device including in combination a plurality of upwardly converging rod-like guides, means for spacing said guides from each other and holding them in substantially vertical position, material receiving means vertically slidable on and supported by a single guide, and freely movable thereon to be held by gravity within said guides.

2. A material handling device including in combination two pairs of rod-like guides to beheld in substantially vertical position but converging slightly upwardly, spacing,

members connecting the members of each pair, said guides being uniform throughout Y substantially their entire length, means for holding said spacing members in crossed relation to each other, and a material receiving member vertically movable on said guides. Y

3. A material handling device including in combination two pairs of rod-like guides to be held in substantially vertical position v but convergingslightly upwardly, spacing members engaging only the upper ends of i the guides and connecting the guides of each pair, means for holding said spacing members in crossed relation to each other, material receiving means vertically movable on said guides and held inwardly of the guides by gravity.

In testimony whereof, I have signed my name to this specification.
